Magnetic resonance cholangiopancreatography (MRCP) is a medical imaging technique. It uses magnetic resonance imaging to visualize the biliary and pancreatic ducts non-invasively. This procedure can be used to determine whether gallstones are lodged in any of the ducts surrounding the gallbladder .
There are at least four types of cholangiography: [citation needed] Percutaneous transhepatic cholangiography (PTC): Examination of liver and bile ducts by x-rays. This is accomplished by the insertion of a thin needle into the liver carrying a contrast medium to help to see blockage in liver and bile ducts.
Advantages of ultrasound imaging of abdominal structures are that the procedure can be performed quickly, bed-side, involves no exposure to X-rays (which makes it useful in pregnant patients, for example) and is inexpensive compared to other often-used techniques such as computed tomography (CT scan) of the abdomen. Disadvantages are ...
ERCP can be performed for diagnostic and therapeutic reasons, although the development of safer and relatively non-invasive investigations such as magnetic resonance cholangiopancreatography (MRCP) and endoscopic ultrasound has meant that ERCP is now rarely performed without therapeutic intent. [2]
The investigation is usually conducted after an ultrasonographic examination of the abdominal right upper quadrant for a patient presenting with abdominal pain.If the noninvasive ultrasound examination fails to demonstrate gallstones, or other obstruction to the gallbladder or biliary tree, in an attempt to establish a cause of right upper quadrant pain, a cholescintigraphic scan can be ...

Trans T-tube technique of stone extraction also known as Burhene technique. This procedure is done after 5 to 8 weeks post abdominal operation for the maturation of the T-tube tract when fibrous tissue is formed at its walls to support the tract and keep the tract open. [11] Guidewire is then advanced through the T-tube before the T-tube is ...
